Suspicion/fear and grandiosity and/or a mystical experience. Such awareness that it's possible to rewind/repeat what you've seen in your mind. Interesting that that happens (to others as well).

I try to forget the details if I even remember them (I very well remember them for maybe a month and some things I have seen I can still remember after many years in great detail, like a traumatic experience, in a way). If incongruent psychosis happens during mania I don't remember much of it and it's less noticeable, it's more difficult to discern the break, for me, but generally more so for others than "pure" mania). I don't think the details are important. The experience is worthwhile but not because of exactly what you think (why and emotions and dynamics are important, not the nonsensical ideas and reasoning).

I (also) really don't like to think about it.
